A record harvest is coming and coffee prices went up anyway

On 22 July the USDA raised its forecast for the 2026/27 world coffee crop to a record 189.7 million bags. Nine days later arabica futures closed the week up 5.83 percent. Those two facts sit oddly together only if you assume the price is watching the harvest.

The forecast that should have cooled the market

This is not a small revision. The USDA forecast puts world output up 6.0 percent, or 10.8 million bags, on the previous season, with arabica up 12 percent while robusta slips 0.7 percent. World ending stocks are seen rising 1.9 million bags to 26.3 million. Brazil alone is put at a record 71.9 million bags, against 63 million a season earlier.

None of that is strange news in itself. Origins recover, and Mexico is at a ten-year high on the same trend. What is strange is the price response, or the absence of one.

What certified stocks actually are

A futures contract is not settled with a forecast. It is settled with green coffee that has been shipped, graded and accepted into an exchange-approved warehouse, and that pile has a name: certified stocks. It is the only coffee the contract can actually deliver.

On Friday 1 August the certified arabica pile on the ICE exchange in New York fell to 264,179 bags. The week took 47,138 bags out of it, the steepest weekly drawdown in a long time.

Why do the two numbers not meet?

Scale, first. A world crop is counted in millions of bags and the certified pile in hundreds of thousands, so the two sit three orders of magnitude apart. Timing, second. A forecast crop has not been picked, dried, shipped or graded, and each of those steps takes months. The USDA circular is explicit that it publishes estimates rather than deliveries.

Then there is the question of which coffee gets certified at all. Grading costs money and warehouse space costs money, so lots go to the exchange when that is the best available outlet and stay with their buyers when it is not. A record coffee harvest can sit alongside a thin warehouse for a whole season.

What the price actually did

The arabica September contract closed that Friday at $3.3210 per pound, up 5.83 percent across the week. Nothing about the harvest changed in those five days. The deliverable pile got smaller, and the contract that has to settle against it got dearer.

Whether that holds is a different question and not one to answer here. Coffee prices have a long record of moving on the thing nobody put in the headline, and the collapse of 1989 is the extreme version of the same lesson.

How to read the next headline

Two different numbers get called the coffee price in ordinary reporting. One is a production forecast, published a few times a year and revised often. The other is a warehouse count, published every trading day, and it is the one a futures screen reacts to.

When the next record harvest story appears, check which of the two it is quoting. If the piece is counting bags in the millions, it is describing a crop somebody still has to pick.
